Although home teams are only winning 42% of the time in this year's post-season, teams that scores first are winning 83% of the time. That seems hard to believe with the well publicized comebacks by Washington (down 3-0), Boston (also down 3-0) and San Jose (down 4-0).
Prior to this season, teams that scored first were generally winning between 60-70% of games which is probably a good statistic when compared to the pre-lockout era. When obstruction reined free in the NHL it was common for teams to try to sit on a 1-0 lead for 40 or 50 minutes. Pretty boring hockey. After the lockout when offensives began to open up sitting on a lead became more difficult.
So what has happened?
I'm not sure. It doesn't appear that obstruction has returned to the pre-lockout levels. We are only talking about 35 games so perhaps this post-season is just an anomaly. Still it may be something of a concern if it continues.
